If you’re a couch potato, get moving. Your life could depend on it.
Researchers say replacing 30 minutes a day of sitting with physical activity could cut your risk of premature death by nearly half.
They examined 14 years of data on inactivity and activity with more than 92,500 people in an American Cancer Society study.
Among those participants who were least active (less than 17 minutes a day of moderate to vigorous physical activity), replacing 30 minutes of sitting with light activity was associated with a 14 percent reduced risk of premature death.
